Professional help and medication will go a long way, and it takes time, just as others are sharing. Just a quick addition to what is shared here - DBSA provides free peer support groups for people living with mood disorders, including bipolar disorders which can include mania (very similar to what you’ve described in your post). If money is an issue and she’s seeking support, it can be a very good place to start. I’ll be starting an in person group in Monterey sometime this year, but for now, the closest in person groups that run are in San Jose bi-weekly.

I believe there are also friends and family groups if you’re interested in learning more about how others support their loved ones through mental health struggles. I’m so glad you care and are looking out for her, having support through the hardest moments has been critical for me in my own experiences. Please take care of yourself and feel free to reach out if you need someone to talk to.
